A Mobile ad hoc network (MANET) is a selforganized system comprised of multiple mobile wireless nodes. In network topology and the absence of centralized administration in management, MANETs are vulnerable to attacks from malicious nodes. To conquer this, a Dynamic trust prediction model is proposed in this paper. This model is used to calculate the trust value, which is based on the nodes past behaviors through extensive fuzzy logic rules prediction. By using this, dishonest nodes can be eliminated, and to obtain a reliable packet delivery route that alleviate the attacks from malicious nodes. The protocol used here is Trust Based Source Routing (TSR) that provides a flexible and possible approach to choose the shortest route that meets the security requirements of data packet Transmission. Several experiments have been conducted, to evaluate the efficiency of the proposed mechanism in malicious node detection. The results show that TSR improves packet delivery ratio and reduces average end-to-end latency.
